Referring to the drawings the numeral 10 designates a preferably cylindrical receptacle having a bottom 1l and removable top 12. The upper end ot the body of the recep tacle provided with an inturned flange i3 and a gasket 14 is arranged between this flange and the top 1.2. An annular flange .l5 is preferably fornied on the top l2 to tele scopically receive the upper end of the body of the receptacle. A suitable handle i6 is secured to one side of the receptacle as shown in Figure l.

A preferably cylindrical auxiliary conerspective of the pump 1perspective of the lling cap' in posi tainer 17 is arranged in the bottom oit thereceptacle and preferably snugly fits therein. The auxiliary container is provided 'with an open lower end, the lower edges of the body of the container resting upon the bottoni Ill.; While the container is provided with an upper head 18. One side ot' the cylindrical portion of the container 17 is provided with a slot 19 vmnlcndinggf from the lower end thereol'l and this slot is adapted to slidably receive a rib 20 projecting inwardly from the cylindrical Wall ot the container l0. It will be apparent that the slot and rib construction described is wprovided for the purpose of insuringV the proper arrangement oft e container l? with in the receptacle l0.

A sleeve or stern 21 is arranged centrally in the lower end of the device and is provided with an axial passage 22 and a radial open- Eli (lll

ing 23 communicating therewith. The lower end of the stem 21 is provided with a shoulder 24 which seats against the bottom 11 and the lower extremity of the stem may be riveted to secure it to the bottom 11 as indicated at 25. The u per end of the stem is provided with an en ar ed axial assage 26 the lower end of which orms ava ve seat 27 ada ted to be engaged by a valve 28. This valve is preferably semi-s herical and is provided with a reduced nec 29 having an annular flange 30 thereabove. The lower end of a coil sprin 31 is reduced to snugly t around the nec 29. A combined guide, sto and spring retainer 32 is arranged above tlie valve 28 and is provided with an upper shank 33 slidable within a tube 34, the lower end of this tube being threaded in the upper end of the stein 21. The tube 34 is provided near its lower end with an internal shoulder 35 a ainst which seat opposite projections 36 carried by the member 33. The latter member is provided with a relatively long depending shank 37 adjacent the up er end of which is a air of projections 38 orming a reduced nec 39 about which the u per extremity of the sprin 31 is coiled, us it will be ap arent t at t e valve'28,cspring 31, and mem r 33 are secured together whereby all may be simultaneously inserted into and removed from the device. i

The upper end of the tube 34 projects through the top 12 and is externally t readed for connection with a connecting member 40 having an annular groove 41 formed therein for a purpose to be described. -Since the member 40 is threaded on the tube 34 and contacts with the top 12, it is adapted to retain the latter element in position on the upper end of the receptacle 10. Aspout 42isthreadedin the upper end of thc member 40, the lutter having a central passage therethrough communicatin between the tube 34 and spout 42.

A cylin er 43 is arranged centrally in the lower portion of the receptacle 10 an is provided with a lower end 44 surrounding the stem 21 and seating upon the shoulder 24. The upper end of the cylinder 43 plrojects through an opening 45 formed in the ead 18 and receives a reciprocating piston 46. A coil spring 47 is arran ed between the head 44 of the cylinder and t e lower end of the piston to normally urge the latter upwardly. An operating stem 48 is arranged in the container 1() and is provided with a forked lower end 49. The extremities of the forked portion are turned inwardly as at 50 for reception within openings 51 formed in the up er end of the piston 46. The upper end of t e stem 48 extends through an opening 52 formed in the head 12, portions of the metal surrounding the opening 52 preferabl being turned upwardly slightly as indicate in Figure 1 to form a seat adapted to be engaged by a felt washer 53 or similar sealing means. A coil lthe mem spring 54 surrounds the stem 48, the spring contacting at its upper end with the washer 53 and at its lower end with a collar 55 secured to the stem. It will be apparent that the stem is slidable in the washer 53, and the sprin compresses the washer and retains it in sea position to prevent leakage of oil through the opening 52. The upper end of the stein 48 is provided with a nut 56 having a preferably round top 57. A preferably broad operating handle 5 is provided with an opening 59 to receive the top of the nut 56, and the inner end of the handle is forked as at 60 for recaption withinthe annular roove 41. The inner end of the handle isy referabl turned downwardl whereb the orked en thereof substantia ly fills t e space between the top and bottom of the groove 41, thus preventing upward movement of the handle ,yond the position shown in Figure 1 so as to prevent the o ning 59 from becoming disengaged from t e nut 56.

A vulve ca c 61 is threaded at its inner end in the wall o the c linder 43 and is adapted under certain con itiona to establish communication between the cylinder and the interor of the auxiliary container 17. The outer end of the cage is turned inwardly as shown to form a seat for a valve 62 which is identical in construction with the valve 28 and need not be referred to in detail. A member 63 is arranged in the inner end of the cage 61 and is similar in general construction to the member 33 previously described except that its structure is changed to accommodate it to the valve cage. The members 33 and 63 are both formed of flat metal stock stamped out in the shapes indicated. The member 63 also is provided with a shank 64 having a spring engaging neck at its inner end adapted for connection' with a sprin 4 65, the outer end of this spring encircling t e neck of the valve 62. It will be noted that the inner end of the valve cage is turned inwardly as at 66 to retain the member 63 in position, the intumed portion being provided at diametrically op 4 ite points with slots 67 in which ments of the valve structure as a whole are assembled. One side ofthe auxilia containeris rovided .with apair of inward y extending ns 68 adapted to be arranged on op site sides of the valve cage 61 to retain the latter in proper position with respect to the auxiliary container for a purpose to be described. In this connection it will be noted that the valve cage is arranged in the side of the receptacle 10 opposite the handle 16.

As previously stated the auxiliary container is slidable in the receptacle 10 and is retained in position by a s ring 69 the u r end of which contacts wit the top 12. is container is provided for the urpose of retaining oil in proximit to t e valve to supply oil thereto to pumped fromc:

r 63 may be inserted when the ele-A employed in connection with the handle 58 in view of the structure thereof. As previously stated, the bent innerl end of the handle serves to till the space between the side walls of the groove 41, thus preventingr the handle from moving upwardly beyond the position shown in Fi ure 1. 1t will be apparent therefore that t e handle cannot become disconnected from the device when in normal osition, and when it is being moved downwar ly the downward pressure exerted against the handle causes the opening 59 to remain in position around the head 57. From the foregoing it will be apparent that most of the elements of the device are adapted to be retained in posi tion without positive/fastening means, and

the cost of manufacturing the device is thus minimized and asselnbling and disassembling are greatly facilitated.-

Particular attention is invited to the struc- `ture and operation of the two check valves employed. Each check valve per se is rovided with the reduced neck described w ich is ada ted to receive the similarly reduced end o the corresponding spring whereby these elements are secured together. Similarly, the opposite ends of the springs are connectedto the retaining members 32 and 63, and accordingly it will be apparent that the elements which constitute the valves and asso- 35 ciated elements are adapted to be inserted and removed from the device as a unit. The upper check valve may be removed simply by unscrewing the tube 34 and lifting the member Sil. The lower check valve and associated eleau ments may be removed by revolving the member 61 until the edges thereof register with the slots 67 whereupon it may be withdrawn through the inner end of the cage 61.

It is to be understood that the form of the invention herewith shown and described is to be taken as a preferred example of the same 'and that various changes in the shape, size and arrangement of parts may be resorted to without departing from the spirit of the invention or the scope of the subjoincd claims.
